Symposium: Insect Behavioral Ecology--'92: Introduction of Exotic Entomopathogenic Nematodes (Rhabditida: Heterorhabditidae and Steinernematidae) for Biological Control of Insects: Potential and Problems

Richard K. Jansson

Abstract


Interest in the use of entomopathogenic nematodes (Heterorhabditidae and Steinernematidae) as biological control agents of insect pests has grown rapidly in recent years. As a consequence, there has been an increase in the numbers of soil surveys for these nematodes worldwide. These surveys have isolated large numbers of feral nematodes, some of which are new species and strains. It is anticipated that considerable exchange of nematode germplasm will occur between various laboratories. Some of these exchanges may result in the introduction of exotic nematodes into non-native lands. The present paper reviews the potential and concomitant risks of nematode introductions into non-native lands.
